anyone who has run a marathon or knows a marathon, people are throwing bags everywhere, they're exhausted, looking for family members. now they're going through whatever may be, whatever materials may still be here. it is a lot. i will tell you this, marathon will happen next year. it will be different. the finish line will probably be different. i was head of homeland security for the state. it was a big part of planning the marathon. the problem is, of course, the finish line, as you said, is very open. you want it to be open. people are running into family members' arms, it's very joyous. there are be more precautions at finish line. no one believes marathons can be safe. it's 52 -- i'm doing math wrong -- 26 times 2 miles of spectators on both sides of the road and you can't make them perfectly safe. so you have procedures and processes in place to ensure that people are looking out for bad things happening and that the first responders know what to do if something does. >> you've got great insight here. so share some of it with us, if you will. president meeting with cabinet member,
